Have loaded one thousand rds for use in my LC Carbine and Thompson 1927A1. Feeds and fires completely in each with much better than suitable accuracy. My new go-to bullet for enjoyable plinking. This bullet consists of a swaged guide Main, which is completely enveloped by its electroplated copper jacket. https://reidwhqzj.targetblogs.com/39234421/helping-the-others-realize-the-advantages-of-100-grain-9mm-bullets-for-reloading
